一. 问题

        升级 VSCode 后,不知啥时候,python debug 的时候,提示 Python 解释器路径无效 ?

        网上搜了一大堆无用的信息,也不管用的,哎,只能自己去官网折腾和鼓捣了;

总之:

  •  python.pythonPath 从settings 中完全删除是一个巨大的破坏性更改;

-- 此对话已被锁定为过于激烈且仅限于合作者。

二. 环境

        环境信息, 如下所示:

# VSCode
版本: 1.57.1 (Universal)
提交: 507ce72a4466fbb27b715c3722558bb15afa9f48
日期: 2021-06-17T13:28:32.912Z
Electron: 12.0.7
Chrome: 89.0.4389.128
Node.js: 14.16.0
V8: 8.9.255.25-electron.0
OS: Darwin x64 19.4.0

# Python
python: 2.7 ❌
python: 3.9 ✅
ms-python.python: v2021.6.944021595
ms-python.vscode-pylance: v2021.6.2

三. 解释

        参考:

                1. https://github.com/microsoft/vscode-python/wiki/AB-Experiments#tldr

                2. https://devblogs.microsoft.com/python/python-in-visual-studio-code-may-2020-release/

                3. 弃用 PythonPath

        有如下信息:

  • The python.pythonPath setting is no longer used by the Python extension.
  • A new optional setting python.defaultInterpreterPath is introduced in the user and workspace scope, from which the extension will read the value when loading a project for the first time.
  • Changes to the python.defaultInterpreterPath will not be picked up by the Python extension once an interpreter is already selected for the workspace. The extension will also not set nor change the value of this setting, it will only read from it.
  • A VSCode internal storage is introduced which will now store the interpreter settings in the workspace & workspace folder scope. i.e workspace settings are no longer stored in settings.json/.code-workspace, but an internal storage.
    • You can change the value stored in workspace settings using Python: Select Interpreter command.
    • See the Python output channel to check the value of the interpreter selected.
    • You can clear the value stored using Python: Clear Workspace Interpreter Setting command.

啥意思呢?

我用机器翻译一下:

  • python.pythonPath: Python 扩展不再使用该设置。
  • python.defaultInterpreterPath: 在用户和工作区范围中引入了一个新的可选设置,扩展将在首次加载项目时从中读取值。
  • python.defaultInterpreterPath: 一旦为工作区选择了解释器,Python 扩展就不会获取对的更改。扩展也不会设置或更改此设置的值,它只从中读取。
  • 引入了 VSCode 内部存储,现在将解释器设置存储在工作区和工作区文件夹范围内。即工作区设置不再存储在 settings.json/.code-workspace 中,而是存储在内部存储中。


                - 您可以使用Python: Select Interpreter 命令更改存储在工作区设置中的值。
                - 查看 Python 输出通道以检查所选解释器的值。
                - 您可以使用Python: Clear Workspace Interpreter Setting 命令清除存储的值。

哎,一言难尽

        Path to Python, you can use a custom version of Python by modifying this setting to include the full path. This default setting is used as a fallback if no interpreter is selected for the workspace. The extension will also not set nor change the value of this setting, it will only read from it.

翻译(引用):

        对于Python的路径,您可以通过修改此设置以包含完整路径来使用自定义版本的Python。如果没有为工作区选择解释器,则此默认设置用作回退。扩展也不会设置或更改此设置的值,它只从中读取。

环境自动选择过程,如下:

  1. 选择具有最新Python 版本的环境
  2. 按字母顺序选择第一个

        如果想在状态栏得到 "Select Python Environment" 的提示,可以设置 "Select Python Environment" : " " ,重启 VSCode 即可;

        The "python.pythonPath" setting in your settings.json is no longer used by the Python extension. If you want, you can use a new setting called "python.defaultInterpreterPath" instead. Keep in mind that you need to change the value of this setting manually as the Python extension doesn’t modify it when you change interpreters. Learn more.

下面给出解决方式;

四. 解决

工作区解释器的路径现在将存储在 VS Code 的持久存储中,而不是settings.json 文件中;

您可以使用Python: Select Interpreter 命令更改特定于工作区的值。在命令面板上使用该命令时,存在一个新选项来指定解释器路径。

五. 测试

Python 2.7Python 3.8备注
VSCode(1.57.1 (Universal))

遗留与说明:

  1. Python 2.7 问题,没有 Debug 执行成功,依然提示设置 Python 解释器路径无效,怀疑 VSCode 慢慢再摒弃 Python 2.x 的支持力度;
  2. Python 3.8,目前 Debug 执行成功的;

(完)

<think>嗯,用户遇到了conda创建环境时出现无法加载配置文件.condarc的错误,需要帮忙解决。首先,我得回想一下常见的conda配置问题。可能的错误原因包括.condarc文件权限问题、格式错误,或者路径问题。 首先,权限问题。.condarc文件如果权限设置不正确,conda可能无法读取。用户可能需要检查文件的权限,确保当前用户有读取权限。比如在Linux或Mac下,可以用chmod修改权限。另外,如果用户误操作修改了权限,也会导致这个问题。 然后是文件格式错误。.condarc是YAML格式的,缩进和语法必须正确。比如,冒号后面需要有空格,列表项对齐正确。常见的错误可能包括多余的缩进、缺少冒号或者使用了tab而不是空格。用户可能不小心编辑了这个文件,导致解析失败。这时候可以建议用户检查YAML语法,或者暂时重命名.condarc文件,让conda使用默认配置,看是否能解决问题。 还有路径问题。conda会在多个位置查找.condarc文件,比如用户主目录、conda的根目录等。如果用户的环境变量配置有问题,或者文件被放到了错误的位置,conda可能找不到或者加载错误的配置文件。这时候需要确认.condarc的位置是否正确,通常是~/.condarc或者%USERPROFILE%\.condarc。 另外,用户可能遇到环境变量冲突,比如CONDA_CONFIG_PATH被错误设置,导致conda去错误的路径找配置文件。这时候检查环境变量,或者临时取消设置这些变量可能会有帮助。 解决方案方面,逐步排除问题比较有效。首先检查文件权限,然后验证YAML格式,可以用在线工具检查。如果问题依旧,尝试重命名或删除.condarc,让conda重建。另外,检查文件路径是否正确,是否存在多个.condarc文件冲突。如果用户之前修改过配置,可能不小心引入了错误。 用户的问题中还提到了其他引用,比如关于TensorFlow的CUDA错误和pip的CA证书问题,这些可能不直接相关,但需要注意是否在配置conda时涉及到了环境变量或其他配置冲突。比如,如果用户修改了全局环境变量,可能影响到conda的行为。 总结下来,解决步骤可能是: 1. 检查.condarc文件权限。 2. 验证YAML格式是否正确。 3. 临时移除/重命名.condarc文件测试。 4. 检查文件路径是否正确,是否有多个配置文件。 5. 检查环境变量是否有冲突设置。 需要一步步引导用户进行排查,确保每个可能性都被覆盖。同时,提醒用户备份配置文件,避免数据丢失。如果用户不熟悉YAML语法,可以建议使用在线验证工具,或者手动检查常见错误点,比如缩进、冒号后的空格等。</think>### 解决conda创建环境时无法加载.condarc配置文件的步骤 #### 1. **检查文件权限问题** - **现象**:若`.condarc`文件权限被错误设置(如无读取权限),conda无法加载配置 - **解决方法**: - Linux/macOS: 执行命令 `chmod 644 ~/.condarc` 修改权限 - Windows: 右键文件 → 属性 → 安全 → 检查用户权限是否包含"读取" - **验证方法**:临时移动文件 `mv ~/.condarc ~/.condarc.bak`,尝试创建环境测试 #### 2. **验证YAML格式正确性** - **关键点**:`.condarc`需严格遵循YAML语法规范 - **常见错误**: - 使用Tab缩进(必须用空格) - 键值对缺少冒号或格式错误(如`channels: defaults`应为`channels: [defaults]`) - 列表项未正确对齐 - **工具验证**:通过[在线YAML验证器](https://yamlvalidator.com)检查配置文件 #### 3. **处理文件路径问题** - **配置文件优先级**: - 系统级路径:`<conda_root>/.condarc` - 用户级路径:`~/.condarc`(Linux/macOS)或 `%USERPROFILE%\.condarc`(Windows) - **排查步骤**: ```bash # 检查所有可能路径 conda config --show-sources # 显式指定配置文件测试 conda create --config ~/custom.condarc -n test_env python=3.8 ``` #### 4. **环境变量冲突检查** - **相关变量**: ```bash echo $CONDA_CONFIG_PATH # 异常设置会导致路径覆盖 echo $CONDA_ROOT # 检查conda根目录是否正确 ``` - **临时清理测试**: ```bash unset CONDA_CONFIG_PATH # Linux/macOS set CONDA_CONFIG_PATH= # Windows cmd ``` #### 5. **典型错误案例解析** - **案例1**:错误添加SSL验证配置 ```yaml # 错误写法(缺少列表标识) ssl_verify: true channels: defaults ``` ```yaml # 正确写法 ssl_verify: true channels: - defaults ``` - **案例2**:代理配置语法错误 ```yaml # 错误写法(未转义特殊字符) proxy_servers: http: http://user:pass@proxy.com:8080 ``` ```yaml # 正确写法(使用URL编码) proxy_servers: http: http://user%40domain:pass%23@proxy.com:8080 ``` #### 6. **高级调试方法** - **生成诊断报告**: ```bash conda info --all > conda_debug.log 2>&1 ``` - **关键日志段解析**: ``` DEBUG conda.gateways.disk.read:is_conda_environment(52): ... ERROR conda.base.context:load_file_configs(714): Invalid yaml at /home/user/.condarc ```
